Axial load carrying capacity

With increasing axial load, the contact conditions in the bearing change. The contact angle and especially the size of the contact ellipses increase, and there may be increased stress at the ring shoulder/raceway transitions. This stress is kept to a minimum for SKF super-precision bearings by appropriate measures, such as rounded and ground transition zones. Even so, the guideline values for the maximum axial load (→ product table) should not be exceeded.
